Initially, this field was intended and used in an affirmative sense, as in
"this subscription type should be publicly visible". Since this will be
true for most subscription types, the UI was changed to "this subscription type should *not* be publicly visible" to not have to require Subscription Managers to have to click on the checkbox each time that they create a new subscription type.
To further clarify this new behaviour, update the following for consistency:
- rename the database column
- rename the getPublic method
- modify the getPublic code to refer to the new column name
- rename the calls to the new getPublic method

- Improve column name.
- Since subscription types will now be visible in areas (i.e. payments) other than just About, modify the following text:
"This subscription type will not appear under Subscriptions in About the Journal."
to something more generic, i.e.:
"This subscription type will not be publicly visible (e.g., under Subscriptions in About the Journal)."
